OKLAHOMA CITY — Suddenly, these Golden State Warriors who have been compared all season to the Chicago Bulls dynasty of the 1990s are on the brink of elimination.

Russell Westbrook had 36 points, 11 rebounds and 11 assists, and the Oklahoma City Thunder beat the Warriors, 118-94, on Tuesday night to take a 3-1 lead in the Western Conference Finals. Golden State, which won a league record 73 games in the regular season, lost consecutive games for the first time this season.

The Warriors must win Game 5 on Thursday night in Oakland, Calif., to keep their season alive.

“We all have to bounce back,” Warriors coach Steve Kerr said. “The good news is, we go home. Obviously we play well at home. The idea now is to go home and get one win. Do that, and we put some pressure on them and we'll see what happens.”

Klay Thompson led Golden State with 26 points, but two-time league Most Valuable Player Stephen Curry was limited to 19 points on 6-for-20 from the field. Curry's shooting performance was so uncharacteristic that reporters asked whether he was hurt.

“He's not injured,” Kerr said. “He's coming back from the knee, but he's not injured. He just had a lousy night. It happens, even to the best players in the world.”

The Warriors lost consecutive playoff games by at least 20 points for the first time since games 2 and 3 of the 1972 Western Conference semifinals against the Milwaukee Bucks. Golden State's Draymond Green, who was fined for kicking Steven Adams in the groin in Game 3, finished with six points, 11 rebounds and six turnovers.

Meanwhile, Oklahoma City got a boost from an unlikely source. Andre Roberson, a player the Warriors have ignored at times during the series, scored a career-high 17 points and grabbed 12 rebounds.

Kevin Durant added 26 points and 11 rebounds and Serge Ibaka added 17 points and seven rebounds.

As for Westbrook, it was his first triple double of the playoffs after posting 18 in the regular season. It was his fifth career playoff triple double.

“I play every game like it's my last, regardless of who's in front of me,” he said. “That's my job, and my job is to worry about my team, and that's all I do.”

The Thunder know they have to close. Nine teams have rallied from 3-1 deficits to win.

“I think we're in a good place, but like I said, this game is over,” Westbrook said. “We've got to move on to the next game. Every game is different.”

The Thunder led 30-26 at the end of the first quarter, then gained control in the second. In the most unlikely of connections, Adams threw a bullet pass to Roberson near the basket for a dunk that gave the Thunder a 56-43 lead.
